Tioga manufactures mountain bike components such as pedals, saddles, and their unique disk wheel. They manufacture one tire, called the Psycho, in different tread patterns and rubber compounds for front and rear use.

The review is divided into two parts. First, a chart rates the tire's performance on four kinds of terrain on a scale of 1 to 10. Click on the tire's name in the chart to jump to the second part of its review, below the chart: a written description of the tire's construction and its handling characteristics on different kinds of terrain, and a link to a picture of each tire's tread.

Rear Use: The Psycho's rounded profile and sharp edge knobs make it roll smoothly and corner firmly and predictably even in very hard leans. When climbing it digs into soft ground but its knobs aren't quite tall enough to produce excellent traction. Its knobs are slightly closer spaced than the best mud tires, and pack with mud quicker. On hard dirt it climbs well aided by its light weight and fast rolling. Its rounded profile makes its contact area on rocks too small for excellent climbing traction. The Psycho's edge knobs feel predictable at all lean angles when cornering. On soft dirt they are too blunt to cut in but they still feel firm and consistent. On hard dirt and roots and rocks the large stiff knobs hold without flexing or slipping. It brakes well when leaning because of its rounded profile and stiff knobs. It doesn't skitter sideways when braking in a straight line but also doesn't slow down quickly. The casing resists cuts well but the rubber chips and wears quicker than most tires. Pavement riding wears the knobs even though they roll smoothly. The Psycho makes an excellent XC racing tire in hard conditions and works well for trail riding in most conditions, especially when gravel or tar roads are part of the terrain. Its width and limited braking traction make it unsuited for downhill racing, despite its good cornering traction.
